Installation on a Mac with 64-bit architecture

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Installation following the installation page on a machine with 64-bit 
architecture
2.
3.

What is the expected output? What do you see instead?
I got the following warnings when running 'python setup.py 
--with-minuit=(pathname to 
Minuit-1_7_9)'

ld: warning: in 
/Users/lisa/installations/Minuit-1_7_9/src/.libs/liblcg_Minuit.dylib, file is

required architecture
ld: warning: in 
/Users/lisa/installations/Minuit-1_7_9/src/.libs/liblcg_Minuit.dylib, file is

running install_lib

When I import into python, I get the following error:
In [1]: import minuit

On OS X, the name of the relevant environment variable is "DYLD_LIBRARY_PATH".  
The installation instructions have been updated.

I have a similar (or same?) problem using Mac OS 10.6.6 with python installed 
from http://python.org/download/releases/2.6.6/ .  I installed pyminut and 
Minuit from /usr/local/src/* using sudo.  Setting DYLD_LIBRARY_PATH, 
DY_LIBRARY_PATH, nor LD_LIBRARY_PATH does not help.  Note that current MAC OS 
instructions include:

% export DYLD_LIBRARY_PATH=/location/of/Minuit-1_7_9/src/.libs:$DY_LIBRARY_PATH

I suspect that it is either DYLD_... or DY_... but not both.

The Minuit build had a few warnings but did not end with a fatal error:

FF:pyminuit $ pwd

FF:pyminuit $ sudo python setup.py install

The error I get when loading minuit is:

Traceback (most recent call last):
  File "<string>", line 1, in <module>

Note difference of "Expected in: dynamic lookup" vs. "flat namespace" of 
original post.  But the missing symbol is the same.

I am still unable to get this working on my Mac Pro.  I agree with the second 
post, changing the environment variable was not a fix.  I get the same error 
when trying to import minuit into python.

dlopen(/Users/lisa/lib/python/minuit.so, 2): Symbol not found: 
__ZN13MnApplicationclEjd
  Referenced from: /Users/lisa/lib/python/minuit.so
  Expected in: flat namespace
 in /Users/lisa/lib/python/minuit.so

I checked to see which of the files are missing from the bottom note in the 
installation instructions.  With the standard installation, the files end up in 
the /usr/local/lib instead of /usr/lib.  

Any ideas on the problem?

Same problem, and (as above) changing environmental variable as described in 
the installation instructions does not fix it.  Using Python 2.6.1 
(r261:67515), Minuit 1.7.9.

I get the following error:
 dlopen(/Users/ianc/Downloads/pyminuit/build/lib.macosx-10.6-universal-2.6/minuit.so, 2): Symbol not found: __ZN13MnApplicationclEjd

I am using python 2.6.6 (r266:84374, Aug 31 2010, 11:00:51), and Minuit 1_7_9. 
I'm having the same issues as above.

Exact same problem. Running EPD 7.2.2 (python 2.7) with OS X 10.6.8, and it 
throws an error when I try to import the module:

Symbol not found: __ZN13MnApplicationclEjd

Does this indicate a compile error? Has anyone found a solution or a reason why 
this seems to be happening?

HI, 

Still I have this problem.
On my architecture, error message was 

************************************
File "<stdin>", line 1, in <module>

Is there any way to avoid this problem?
